The compounds were separated by recycling-HPLC, and their structures were determined on the basis of spectroscopic analysis. CD measurements were used to establish the absolute con®guration of the anthrone and oxanthrone. The antifungal activity of 1- O-b-d- and 8-O-b-d-glucopyranosyl emodin against Leucoagaricus gongilophorus was shown to be similar to that of the lignan sesamin. # 2000 Elsevier Science Ltd.
